In this paper, the servo state feedback control of the self balancing robot is proposed. Balancing robot system to control is used ADXL3xx accelerometer as sensors to measure the angle and angle changes and then sends signals to the Servo motor for robot can balance the stability, respectively. Self Balancing robot control are application of MATLAB /(More)
This paper presents the PID controller design for coupled-tank process using characteristic ratio assignment (CRA). The coupled-tank process is a challenge plant for testing the performance of PID controller because it is a high uncertainty nonlinear model. For this paper, the characteristic ratio assignment (CRA) which is satisfied specification of(More)
This paper presents the communication network for machine vision system to implement to control systems and logistics applications in industrial environment. The real-time distributed over the network is very important for communication among vision node, image processing and control as well as the distributed I/O node. A robust implementation both with(More)
Evaluation of a retinal image is widely employed to help doctors diagnose many diseases, such as diabetes or hypertension. From acquisition process, retinal images often have low grey level contrast and dynamic range. This paper proposes histogram analysis for solving the problems of retinal image enhancement. The proposed method uses fuzzy set to enhance(More)
This paper presents the approach to design PID controller for a modified quadruple-tank process using inverted decoupling technique. In case of non-minimum phase, TITO system, such as modified quadruple-tank process which can't be controlled by PID controller with standard decoupling technique because the system can't be stabled by saturating manipulate(More)
This paper presents a flexible manufacturing system (FMS) that cooperated with the holonic manufacturing system (HMS) with automatic material handling devices via industrial networks. The HMS is described as an intelligent manufacturing system that employs multi-agent system with negotiation protocols. The traditional HMS's negotiation protocol usually used(More)
The purpose of this paper is to study and develop the redundant control system for the critical process. The critical process means a high priority process which is very essential to the global system. When a fault condition occurs on such process, it affects to other processes. In this paper, the gas pressure process is used a case study. This system(More)
Laser interferometers have generally been used for the angular measurement of measuring tape calibration systems. Yaw error measurements using a yaw sensor have been carried out to determine the characteristics of yaw errors and analyze the behaviors of the structural guide. The yaw sensor technique is identical to the error compensation used in a measuring(More)
In this paper is presented the multilevel inverter which is controlled by Phase Lock Loop (PLL) controller in close-loop system. The multilevel inverter was multiplied voltage levels at output. The inner PLL controller was controlled by PI control in order to firing angle of PWM signal. This control scheme is estimated phase and frequency in DQ-transform of(More)
